Specops Device Trust: Device-based access control beyond MFA

Configuring Zero Device Trust policies
Specops Device Trust is a cloud-based security product from Specops Software (part of Outpost24) that ties access decisions to user identity and the device's security state. It addresses a specific gap that multi-factor authentication (MFA) alone cannot close: an attacker who steals a session token or login credentials can still access your systems if access decisions are based solely on user identity. The product binds users to enrolled, verified devices and continuously checks device security throughout every session. This article covers how Specops Device Trust works, what it checks, and how to deploy it.

A Chinese threat actor tracked as UTA0565 used fake media and NGO websites to deliver CLEANGULP, a malware family nobody had documented before, to Asian government targets. The group used the Chrome-Windows zero-day chain behind the BlueMoon exploit kit, which has spread across China-linked espionage campaigns. That makes UTA0565 one more operator of a kit that already appears to be shared among several state-aligned groups.

Windows 11 KB5124010 fixes File History backups broken by September update

Microsoft had already confirmed that its September updates can break File History backups. The fix only ships in an optional release, so most PCs will have to wait for the October 13 Patch Tuesday to get it through normal channels.
